 Well, it may not be supported, but that's not the problem in this case:
 
 dino01% ../gcc-3.1/configure
 dino01% make bootstrap > & build.log &
 dino01% tail -40 build.log
 ...
 gnatgcc -c -g  -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional   -gnatpg -gnata -I- -I. -I../../../gcc-3.1/gcc/ada ../../../gcc-3.1/gcc/ada/gnat1drv.adb
 gnatbind -C -I- -I. -I../../../gcc-3.1/gcc/ada -o b_gnat1.c -n gnat1drv.ali

 The problem is that configure finds an installed gnatgcc and a gnatbind *that
 are too old to build the current ada compiler*, but it tries to use them
 anyway.
